12 Small Windmills Put To the Test In Holland

I guess size does matter. Very disappointing.

A real-world test performed by the Dutch province of Zeeland (a very windy place) confirms our earlier analysis that small windmills are a fundamentally flawed technology. Twelve of these much hyped machines were placed in a row on an open plain. Their energy yield was measured over a period of one year, the average wind velocity during these 12 months was 3.8 meters per second (slightly higher than average).
